Specification of Letters Patent.

Patented Nov. 14, 1916.

Application filed September 23, 1915. Serial No. 52,153.

To all whom it may concern Be it known that we, PAOLO CHILLEMI and ANTONIO RANERI, subjects of Italy, residing at Schenectady, county of Schenectady, and State of New York, have invented certain new and useful Improvements in Vashing-hlachines, of which the following is a specification.

Reference may be had to accompanying drawings, and the reference characters marked thereon, which form a part of this specification. Similar characters refer to similar parts in the several figures therein.

Cir

This invention relates to a type of clotheswashing machine having a rotatory dasher with clamping-mechanism for detachably mounting clothes thereupon, whereby the clothes are repeatedly dashed into the washwater or suds in the operation of the machine.

The principal objects of the invention are to prevent injury to the clothes, and to securely clamp irregular bodies of clothing upon the dasher.

Figure 1 of the drawings is a central, vertical section of a washing-machine embodying our invention. Fig. 2 is a crosssection taken through the clothes-clamping mechanism on the broken line 2-2 in Fig. 1. Fig. 3 is a cross-section taken on the broken line 8-3 in Fig. 1, through one of the toothed racks and the forked end of a clamp-bar slidably mounted upon the rack. Referring to the drawings wherein the invention is shown in preferred form, 1 is a tub or vat, and 2 is a dasher fixed upon a shaft, 3, rotatively mounted in bearings in the walls of the vat. The shaft, 8, may be rotated in any known manner as by means of a crank-handle, 4. The dasher, 2, is preferably made in the form of a grid-like casting, terminating at its opposite ends in parallel arms, 5. At each end of the dasher a roller, 6, is rotatively mounted between the ends of the two parallel arms, 5. Extending inwardly from a point adjacent to the roller, 6, is a toothed rack, 7 formed upon each of the arms, 5. A clamp-bar, 8, having forked ends, 9, is loosely mounted upon the respective racks, 7, to slide therealong toward and from the roller, 6; and this clamp-bar, 8, has mounted thereupon a pair of spring-actuated dogs, 10, adapted to engage the teeth on the respective racks, 7, adjacent to the opposite ends of the clampbar. These spring-actuated dogs are adapted to be withdrawn from engagement with their respective toothed racks by means of thumb-pieces or handles, 11, on the respective dogs. The outer side of the clamp-bar, S, is preferably corrugated, as shown at 12, whereby it is adapted to become more or less embedded in the clamped body of clothes.

The operation of the device is as follows: The spring-actuated dogs, 10, are withdrawn by means of the handles, 11, and the clamp-bar is slid inwardly along the respective racks, T, away from the roller, 6. A body of clothes is then inserted between the roller, 6, and the clamp-bar, and the clampbar is forced outwardly toward the roller into close engagement with the interposed body of clothes to clamp the clothes between the roller and the clamp-bar. The clamp-bar is held in such clamping position by the engagement of the spring-actuated dogs, 10, with the teeth on the respective racks, 7. The forked ends of the clamp-bar, 8, fit therespective racks, 7, loosely to permit the clamp-bar to be tilted somewhat relatively to the roller, 6, as shown at the top of Fig. 1, whereby the clamp-bar is adaptable to a body of clothes of variable thickness, and also to permit a slight rocking-movement of the clamp-bar, which, together with the rotative movement permitted by the respective rollers, 6, permits a yielding movement of the clothes in opposite directions, which prevents tearing strains upon the clothes asthey are forced into and through the water, or against the bottom of the vat. At the bottom of Fig. 1, a body of clothes, 13, is shown clamped upon the dasher and immersed in the washwater, 14.

hat we claim as new and desire to secure by Letters Patent is:

In a washing-machine, a dasher having parallel arms and toothed racks extending along said arms; a clothes-clamping roller rotatively mounted between the arms of the dasher; a clamp-bar having forked ends loosely embracing the respective toothed In testimony whereof, We have hereunto racks and slidable therealong toward and set our hands this 11th day of September, 10
